HORSESHOE-MACHENE.

SPECIFICATION forming part of Letters Patent No. 391,779, dated Qotober30, 1888.

Application filed April 14, 1858. Serial No.270,885. (No model) To aZZwhom it may concern.-

Be it known that I, Janus A. BURDEN, of the city of Troy, county ofRenssclaer, State of New York, have invented new and useful Improvementsin Horseshoe Machines, of which the following is a specification.

My invention relates to alnechanism for operating the shaping orentering, the creasing, and the rough-punching rolls of a machine formaking horseshoes, and in which machines it is necessary that the bar ofiron operated upon to produce shoe-blank lengths that are to be shaped,creased, rough-punehed, full-punched, cut off, and swaged shall be movedwith regular periods of motion and alternating periods of rest, it beingthe object and purpose of my invention herein to so move the bar as thusoperated upon by means of a regularly-intermittent motion of the rolls,performing in sequence the several functions of shaping,creasing,andrough-punching, as distinguished from continuously moving rolls thathave upon their perimeters engaging and non-engaging segments,which movethe bar as operated upon with regular periods of motion and alternatingperiods of rest, as shown and described in an application for LettersPatent made by me and filed in the United States Patent Office J anuary7, 1888, Serial No. 260,058, and which is now pending.

Accompanying this specification, to form a part of it, there are sixplates of drawings containing fifteen figures illustrating my invention,with the same designation of parts by letter-reference used in all ofthem.

Of these illustrations, Figure 1 shows a top view of a machine formaking horseshoes from a bar of heated iron by a continuous operation,with my invention, as shown and described herein, applied thereto tooperate the rolls thereof. Fig. 2 shows a side elevation of the samemachine that is illustrated at Fig. 1,with that side of the machine atwhich power is applied to the rolls fronting the view. Fig. 3 is a topview of the three sets of rolls by which the bar is entered, shaped,creased for the nailholes, and rough punched, showing, also, a mutilatedgear of the same peripheral capacity upon each end of the counter-shaftand two mutilated gears of the same pcrimetral capacity upon thedriving-shaft, each of which is adaptedto intermittently engage with oneof the mutilated gears upon the counter-shaft, so as to give to thelatter and the rolls which it operates an intermittent motion, while atFigs. 1 and 2 there is but one set of such mutilated gears used upon thedriving and counter shafts. Fig. 4 is a View of the entering and shapingrolls in elevation and taken with the fronting edges of the rolls asfacing the view, with the driving and counter shafts shown in sectiontaken on the line 00 m of Fig. 3, showing, also, the beveled gear uponthe lower roller'shaft and the beveled gear upon the counter-shaft, andalso the mutilated gears back of said beveled gears. Fig. 5 is an endview of the en tering and shaping rolls and their housings. Fig. 6 is aperspective of the mutilated gear of the countershaft and also that oneupon the driving-shaft. lhis figure illustrates,also,

a promoter arm that is arranged upon the mutilated gear of the countershaft, and it shows,also,a cam-arm that is arranged upon the mutilatedgear that is upon the driving-shaft. Fig. 7 is a section of the enteringor shaping rolls, taken parallel to their sides. Fig. 8 is an edgeelevation of the entering or shaping rolls. Fig. 9 is a diametricalsection of the entering or shaping rolls. Fig. 10 is an edge elevationof the creasing-rolls. Fig. 11 is a diametrical section of thecreasing-rolls. Fig. 11? is an edge elevation of the rough-punchingrolls. Fig. 13 is a diametrical section of the rough-punching rolls.Fig. let is a section of the creasingro1ls,taken parallel to theirsides; and Fig. 15 is a section of the roughpunching rolls, takenparallel to their sides, with the latter shown as turned down upon theiredges instead of being one placed above the other, as in the otherfigures.

The several parts of the mechanism thus illustrated are designated byletter-reference, and the function of the parts is described as follows:

The letter 1? indicates the driving-pulley, and Sits shaft; G, agear-wheel arranged upon the latter to turn with it. This gearwheel Gmeshes into a gear-wheel, G", on the shaft S, which latter is extendedl'rontwardl y to operate the cutting mechanism 0 and the full-punchingmechanism 1? by separate geared connections made therewith.

The letter WV designates a gear wheel arranged on the front end of theshaft S, which gear-wheel meshes into the gear-wheel \V on the shaft Sto communicate motion to the lat ter. The letter M designates amutilated gearwheel, that is arranged on, so as to turn with, the shaftS This gear-wheel Mhas its gears omitted on a portion ofits perimeter,asshown at Fig. 6. This mutilated gear-wheel M is constructed with apromoter-arm, A, that is projected from the wheel so as to move with it.

The letter M designates a mutilated gearwhcel arranged upon the shaft S,so as to actuate the latter when said mutilated gear-wheel M is rotated.This mutilated gear-wheel M is constructed with a cam-arm, A", upon itsside, and where this cam-arm projects beyond its perimeter thegear-teeth thereat are omitted. The function of these mutilatedgearwheels M and M is to operate the shafts S with regular periods ofmotion and alternating periods of rest by having the teeth on the wheelM mesh into those of the wheel M when the gear parts of these perimeterscome together in rotation, and to omit to operate said shafts S* whenthe blank places on the wheel Min rotation are passing over the perimeter of said wheel M The function of the promoter-arm A upon themutilated gearwheel M is to engage with the cam-arm A on the mutilatedgear-wheel M, so as to start the rotation of the latter before thegeared part on the perimeter of the mutilated gear-wheel M commences tomesh into the teeth of the wheel M and to thus in part take off from theengaging teeth the strain of starting the shaft. The gear parts of themutilated gear-wheel M and M are so arranged as to their intermittentengagement that they will (in connection with the movement made by thepromoter and cam) give the shaft S about a half-revolution with analternating period of rest between each half-revolution.

The letters E designate the entering or shaping rolls.

The letters N designate the creasing-rolls, and the letters I therough-punching rolls.

The letter It designates the upper one of the entering or shaping rollsE, and R the lower one of the latter. Each of these rolls is providedwith bearings in the housings H, and the shafts of theseentering-rollers are each constructed with gears that mesh into eachother to communicate power from one to the other.

The letter W designates a beveled gear on the shaft of the lower one ofthe shaping or entering rolls, and this beveled gear 7* meshes intoabeveled gear, D, on the shaft S", by which power is communicated tosaid rolls R and R The letter Rf designates the upper one of thecreasing-rolls N, and R the lower one of the latter rolls, and theserolls are made with connecting-gears 9 by which motion and power iscommunicated from one to the other of them.

The letter W designates a beveled gear on the shaft of the lower roll Rof the creasingrolls, and B a beveled gear-wheel on the shaft The upperroll R of the shaping or enter- 7 ing rolls is plain on its peripheralface, and the lower roll R of this set of rolls has a groove, 9, made inthe roller-face to encircle the latter. This groove,when used to shapethe bar so as to form mud or snow shoes, is made with a bevel, b, on oneof its sides, and this groove is preferably in its cross-section made tobe a little smaller than the entering-bar, so that the bar as receivedand entered will, as each blanklength thereon is shaped, be movedthrough the rolls with expelling force. I

The upper roll R of the creasing-rolls is made with the surface of itsperimeter plain, and the lower roll R of this series is made with agroove, 9, within its perimeter. This groove has two sets ofcreasing-blades, b arranged therein diametrically opposite, each ofwhich at every half-revolution of the rolls creases a blank-length ofthe heated bar for the nail-holes.

The upper roll of the rough-punching rolls has a plain perimetral face,having therein arranged at diametrically-opposite points two series ofsinks, m, and the lower roll R of the rough-punching series is made onits perimetral face with a groove, therein,within which there arearranged at diametrically-opposite points two series of punches, p, andthese two series of punches are each arranged as the two rolls arerotated so that they each of them will come diametrically in line .witheach series of sinks in the upper roll, and each punch of each serieswill come diametrically in line with one of the sinks in the upper rollas these two rough-punching rolls are rotated.

The letter designates a pinion on the driving-shaft that meshes into agear-wheel, P, on the shaft S, by which the swaging and bendingmechanism is operated to shape a blank-length that has been out off fromthe entering end of the bar by the cutting mechanism.

The letters V designate a gear-wheel upon the shaft Siby means of whicha countershaft connection is made to operate the cutting mechanism 0.

The letters W designate a gear-n heel on the shaft S", by which thefull-punching mechan ism is operated.

As thus constructed and arranged,the swag ing and bending mechanism andthe shaft S are constantly moving when the mechanism is running, and thefull-punching and the cutgear-teeth in turning engages with the teethupon the perimeter of the mutilated gearwheel M it during suchengagement will turn the said gear-wheel M until that part of itsperimeter comes around where there are no gears, when it ceases to soturn said mutilated gear-wheel M and the shaft S, which operates thethree sets of rolls, and then the latter stop in their rotation, toagain revolve when the geared segment upon the mutilated gearwheel Magain commences to engage with the gears upon the wheel M The periodicrotation of each of these pairs of rollsis controlled by the amount ofperipheral engagement made between the mutilated gear wheels M and M andthis geared engagement, as herein shown, to be arranged, gives to eachpair of the said rolls a half-revolution with every periodic movementthereof. As shown in the accompanying drawings and as described herein,the periodic movements of these rolls occur simultaneously, and at eachmovement each pair of rolls commences to engage with what will be theentering end of a blank-length at the same time, and also ceases toengage (with what will be the other end of the latter when out off) atthe same instant. The creasing-rolls are keyed to their respectiveshafts, so as to bring each set of the creasing-blades in properposition to locate the nail-creases within each blank-length beingoperated upon at each periodic movement of the rolls and bar, and therough-punching rolls are so keyed to their respective shafts as tocommence the engagement with each blank-length of the bar at the pointwhere the creasing rolls ceased to engage with it, so as to properlylocate the rough punchings within the previously eut nailcreases. A barof heated iron being entered between the shaping or entering rolls, sothatits position therein will insure the action of the latter upon it tothe full extent of a blank-length, said bar is then moved a blank-lengthby the primary set of rolls when the latter cease to turn, and as therolls are again moved by the mutilated gears M and M a succeeding andconnected blank-length is operated upon by the entering orshapingrolls,while the blank length first operated upon has reached thecreasing-rolls, where it is creased for the nailholes. When the rollsstart again to move, the blank-length first operated upon has advancedto the rough-punching rolls, where it is roughpunehed,while the enteringor shaping rolls and the creasing-rolls are operatinguponsucceedingblank-lengths. Afterthe bar has passed beyond therouglrpunching rolls, it

is full-punched, from whence it passes to the swaging mechanism, whereit is cut off and swaged into shape as each succeeding blanklength ofthe bar follows it to be treated in the same manner.-

The full-punching mechanism, the cutting mechanism, and the swagiug andbending mechanism herein shown being the same as are shown in my beforenamed application, and not being claimed herein specifically, they arenot described in detail.

\Vhile I have shown the mutilated gears M and M as applied tocommunicate regular periods of motion and alternating periods of rest tothe shaft which operates the rolls, and as the operation of these rollsas constructed and arranged would be the same if the shaft so movingthem intermittently were so operated by other mechanism than saidmutilated gears, I do not limit my invention to the use of the latter toso operate the shaft which moves them.

As the mutilated gears when used would perform the same function whetheroperated in connection with the promoter-arm of the one and the cam-armof the other, I do not limit my invention so far as the application ofthe mutilated gears is concerned to their combination with the auxiliaryfactors consisting of thepromoter-arm and cam-arm.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s
